This iceberg stands in sharp contrast to another whitish iceberg in the photo which seems to have been taken during the day.
Most icebergs are white except along freshly calved ice cliffs, which tend to appear blue. “Others may appear green, brown or black, or combinations of these colours,” it says.
“The various colorations are caused by differences in density, air-bubble content and impurities,” the encyclopedia explains. “For example, black ice is of high density and bubble free; dark layers indicate the presence of rock materials derived from the base of the parent glacier. Occasionally, rocks may be found on the original upper surface of the iceberg. As the iceberg melts, these materials precipitate into marine or lake sediments.”
The Black Iceberg picture, as it is being referred to online, was posted by Reddit user Rundboll, who did not mention where this picture was taken although other users have been speculating that the image must have been clicked somewhere in New Zealand.
Black icebergs are indeed scarcer than white icebergs, but the Tasman Glacier Lake in New Zealand is known as the ‘home of the black icebergs’.
